Application 1mm 30.1938.' serial No. 227.510 1 oliim. (ci. ca -43)substantiallyl triangular section and increasing in thickness towardsthe invention relates to-the art of shaving devices and moreparticularly to a motor driven shaving device.'

One of the principal objects of my invention is to provide a shavingdevice equipped with a rotary blade or cutter together with shieldingmeans adapted for coaction with the cutter and which is so constructedand arranged as to add to the safety of the device and also eifect inproducing a clean. close shave.

Another object of my invention is to provide a device of the abovedescribed character which can be easily and quickly cleaned so that theusef.u1 life of the device canbe extended for a long period.

A further object of my invention is to provide a device of the abovedescribed character which is simple in construction, durable in use,etlicient in operation and econimical inA manufacture.

Other objects and advantages will belapparent from the followingdescription, appendedclaim and annexed drawing.

Referring to the drawing wherein like reference characters designatelike parts throughout the several views:

Figure 1 is.-.a side elevation vl-of my invention.

Figure 2 is a longitudinal sectional view thereof on an enlarged scale.

Figure 3 is an end elevation of the shield 'and cutter, illustrating thesame` detached from the motor. f

Figure i is a sectional 4 4 of Figure 2.

In practicing my invention I provide a motor ordinary constructionequipped ,with a housview taken on the, line ing in the form of a handleadapted tobe readilyl held in the palm of the' hand. One 'end of saidhousing is equipped with a forwardly extending section 5, the' latterbeing exteriorly threaded and receiving thereon the threaded base end ofa cone-shaped guard or shield I. The guard or shield I is of a hollowconstruction and is fashioned on the outerface thereof with alongitudinally extending rib configuration in cross base end ofsaidguard as clearly illustrated in Figure 2 The ri 1 is romanica aplurality offspaa casing. Said disk I2 is formed with a centrally v tionl and the cutter from the shaft 9 to eifect 1, the latter being of avguardon the opposite side of the latter relative v to said -rib andthereby provide a plurality of spaced teeth 8. Extending from themotorcasing 1 and beyond the section 5 is the motordrive shaft 9 on which isfixed, by means of screws l0, a rotatable spiral conesshapedcutter Il.the edge of which coacts with the teeth 8 on each side of said rib 1 toeil'ect a shearing or shaving of hair when the guard is placed vintoengagement with the face of the operator. By utilizing the rib 1 as arest, the teeth of the guard may be adjusted relative to the face toeiiect a close or substantially close shave upon rotation of said cutter15 by said motor.

A disk I2 effects a closure between said guard and the interior of thecasing whereby to prevent hair and other foreign matter from enteringsaid.

disposed aperture through which the shaft l extends.

From the foregoing it will be apparent that the guard l maybe readilydetached from the secan easy cleansingof the parts.

Furthermore, it will be distinctly understood that various changes andmodifications in the construction and arrangement of the parts may beresorted to without departing from the spirit of the invention or scopeo f the appended claim.

What I claim is:

A device of the character described, comprising, a casing adapted 'tohave mounted therein a motor having a drive' shaft extending beyond saidcasing, a conical-shaped guard connected lto said casing and axiallyreceiving said shaft, said guard formed with a longitudinally extendingrib fashioned with transversely extending teeth terminating about saidguard on the opposite side of the axis of the latterrelative to saidrib. a cutter ixed on said shaft and rotatable by the latter within saidguard for coaction with said-teeth in a manner to eii'ect shavingof theface when said teeth are in engagemnt with said face, and a-diskinterposed between said cutter and said casing for preciuding entranceof foreign matter within said casing.
